Now I'm even more baffled. I emailed Bosch again today. They quote 2.5uH (must be mixing units up) and 6A current.

Those values give calculated dwell of 1.42ms vs their recommended 2.6ms.

Clamp at 6A

I emailed Bosch about dwell times for the MEC coils (MEC717 and MEC718 are same specs, different connector).

They replied (quoted below) suggesting dwell times of 2.6ms at 12v.

Also, the Bosch catalogue at http://apps.bosch.com.au/motorsport/downloads/ignitioncoils.pdf quotes primary resistance of ...

Could this be the reason for my problem? See http://www.msefi.com/viewtopic.php?p=113302

Car (at home now) is now behaving normally, no problem. High compression (11.5:1), long duration cam, 4:1 exhaust with very little restriction (virtually unmuffled).


Can we say with certainty that no one has ...

Bargain. Thanks guys.

Sorry, nuffie here. How is inductance measured? Is this possible for a punter with a multimeter? CRO? Something else? I haven't seen many coil catalogues with this value listed.
